Development of a Limit Avoidance Framework for Active Pilot Cueing

In this paper, previously developed flight envelope protection algorithms and an active control system are integrated in a simulator environment and used as a limit avoidance evaluation framework for fly-by-wire helicopters. A force feedback map is developed and used in a new simulator environment to cue pilots against load factor limits. Adaptive models are developed online and used to calculate allowable control travels on the cyclic controls due to approaching load factor limits. The developed framework is demonstrated for load factor limit avoidance in different simulation scenarios.
